Spinach Cheese Gratin Recipes

Steps:

• Preheat the oven to 400 degrees F (200 degrees C).
• Heat oil in a large skillet over medium heat and cook onion until soft and translucent, about 5 minutes. Season with salt, pepper, and thyme. Sprinkle flour over onion mixture and cook until a thick paste forms, about 1 minute.
• Place spinach in a large soup pot and cover. Heat on low until spinach begins to wilt, about 4 minutes. Turn heat off and add half-and-half, 1 cup Swiss cheese, and the onion mixture. Stir to combine and transfer to a 9-inch gratin dish.
• Combine breadcrumbs and remaining 1/2 cup cheese in a bowl. Pour melted butter over the top and stir to combine. Evenly spread breadcrumb mixture over the spinach.
• Bake in the preheated oven uncovered for 20 minutes. Let cool for 5 minutes before serving.

Steps:

• In a large pot, bring 1 1/2 cups water and 1 teaspoon salt to a simmer. Add spinach; cover and cook until wilted, about 2 minutes. Drain in a colander, pressing out as much liquid as possible with the back of a wooden spoon; coarsely chop.
• In a medium saucepan, melt 2 tablespoons butter over medium. Add shallot and cook, stirring, until softened, about 4 minutes. Add flour; cook, stirring, until mixture is pale golden and has a slightly nutty aroma, 2 to 3 minutes.
• Pour in milk, whisking constantly, until smooth. Cook, stirring constantly along bottom of pan, until bubbling and thickened, 6 to 8 minutes. Remove from heat; add mustard and 1/2 cup cheese. Whisk until smooth.
• In a large bowl, stir together spinach and cheese sauce until spinach is completely coated. Season with salt and pepper.
• Heat a medium skillet over medium. Add remaining 1 tablespoon butter and panko; cook, stirring constantly, until golden brown, about 5 minutes. Season with salt and pepper.
• Preheat oven to 400 degrees. Lightly brush a 7-by-11-inch oval gratin dish with butter. Transfer spinach mixture to dish; sprinkle top with toasted panko and remaining 1/4 cup cheese. Bake until browned on top and edges are starting to bubble, about 20 minutes. Serve immediately.

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Butter an 8 cup (2 l) gratin dish.
• In a skillet over medium-high heat, warm 1 tablespoon butter. Add the spinach and cook, stirring occasionally, until just wilted, 3 to 4 minutes. Press out any excess water. Transfer to a large bowl.
• In a large saucepan over medium heat, melt the remaining 2 tablespoons butter. Add the onions and cook, stirring, until translucent but not brown, about 5 minutes. Add the garlic and then the flour and cook, stirring constantly, until nutty and just golden, about 1 minute. Slowly whisk in the cream and milk and continue cooking until thickened, about 3 minutes. Remove from the heat and stir in half of the cheese until melted. Fold the sauce into the spinach and season with salt and pepper. Transfer to the prepared gratin dish and top with the remaining cheese. Bake until the gratin is golden brown on top, about 10 minutes.

Steps:

• Preheat oven to 400°F. Melt 3 tablespoons butter in medium skillet over medium-high heat. Mix in 2 tablespoons mustard, then breadcrumbs. Sauté until breadcrumbs are golden, about 5 minutes. Cool briefly. Mix in cheese.
